一、状语从句的识别和处理

副词性状语从句也叫状语从句，是指在复合句中做状语的句子，在句中起到副词的作用，可以修饰谓语、非谓语动词、定语、状语、或整个句子。根据状语从句的作用，可以分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。

二、常见引导词

When, as, while, as soon as, before, after, not ...until/till.

Indeed, when one’s memory of an emotionally painful experience leads to serious anxiety, forgetting nay produce relief.(2006 Part B)

Meanwhile, as the recession is looming large, people are getting anxious. They tend to keep a tighter hold on their purse and consider eating at home a realistic alternative.(2010 Part B)

Alvarez’s experience demonstrates the importance of finding ways to diffuse stress before is threatens your health and your ability to function.( 2008-text 1)

三、特殊引导词

除上述连词做引导词之外，这些名词和副词也可以作为引导词，如the minute, the moment, the second, every time, the day, the instant, immediately, directly.

The moment my friend signed his name, he was invited into the manager’s office.

No sooner ...than, hardly ...when, scarcely...when这三个句型结构都表示“一......就......”,否定词在句首，主句需要用部分倒装。

Hardly is the smoke detected when the emergency alarm begins to whistle.

三、省略句型

当从句的主语和主句的主语一致时，时间状语从句可以省略主语和be动词，保留引导词，省略成“when/while+非谓语动词/介词短语/形容词”，主语保持不变

While talking to you, you could-be employer is deciding whether your “wares”and abilities must be displayed in an orderly and reasonably connected manner.(1996 text1)

Peaceful days will eventually come when humans think of others more than themselves.

There will eventually come a day when The New York Times ceases to publish stories on newsprint.(2006 text4)

六、答案解析

1.正确答案: B该题考察状语从句引导词，根据becomes more and more得知从句表示持续和发展中的动作状态，as表明动作的持续,而且两句话动作属于同时发生，因此B为正确项。

2.正确答案: A考察时间状语从句的省略结构。当主、从句主语一致时，从句可以省略主语和系动词。she和walk之间是主动关系，应该使用V-ing形式。因此A为正确项。

3.正确答案: D时间状语从句中no sooner... than, hardly.. when,scarcely... when这几个特殊引导词表示“一....就....，用于句首时，其后谓语动词要用部分倒装。首先排除C项。其次，根据从句began to speak和interrupt的动作顺序来判断，是同时发生的动作，不需要在从句使用过去完成时。因此D为正确项。
